Abstract
Description
Construcción de suelo para hornos de coque horizontales.Floor construction for coke ovens horizontal.
La invención se refiere a un horno de coque en forma constructiva horizontal, un llamado horno de coque Non-Recovery o Heat-Recovery, en el que el suelo de horno de coque está estructurado al menos con dos capas y las capas están formadas por los mismos o diferentes materiales refractarios. La primera capa vista desde la cámara de horno está formada por un material macizo y la segunda capa presenta un gran número de aberturas, hendiduras, huecos, etc., en donde las cámaras de gas de estas aberturas, hendiduras, de estos huecos, etc. están unidas a la cámara de gas del canal de gas de escape que discurre por debajo. Asimismo la invención se refiere a un segmento de suelo, que comprende al menos estas dos capas así como un procedimiento, en el que se usan uno o varios de los hornos de coque citados.The invention relates to a coke oven in horizontal constructive form, a so-called coke oven Non-Recovery or Heat-Recovery, in the that the coke oven floor is structured with at least two layers and layers are formed by the same or different refractory materials The first layer seen from the chamber of oven is formed by a solid material and the second layer presents a large number of openings, crevices, gaps, etc., where the Gas chambers of these openings, slits, of these gaps, etc. are attached to the gas chamber of the exhaust gas channel that runs below. The invention also relates to a segment of soil, which comprises at least these two layers as well as a procedure, in which one or more of the coke ovens are used cited.
El calentamiento de los hornos de coque Heat-Recovery se realiza normalmente mediante la combustión del gas producido durante la coquización. La combustión se controla con ello de tal modo, que una parte del gas por encima de la carga de carbón se quema con aire primario en la cámara de horno. Este gas parcialmente quemado se alimenta a través de canales, que reciben también el nombre de "Downcorner", a los tiros de cuello de la solera de la cámara de horno y aquí se quema por completo mediante la adición de aire de combustión adicional, el aire secundario. De este modo se alimenta calor a la carga de carbón directamente desde arriba e indirectamente desde abajo, lo que influye ventajosamente en la velocidad de coquización y de este modo en la potencia de los hornos.The heating of coke ovens Heat-Recovery is normally performed through the combustion of the gas produced during coking. The combustion this is controlled in such a way that a part of the gas above of the coal load is burned with primary air in the chamber of oven. This partially burned gas is fed through channels, which are also called "Downcorner", to neck shots of the furnace chamber solera and here it burns completely by adding additional combustion air, secondary air In this way heat is fed to the load of coal directly from above and indirectly from below, what which advantageously influences the coking rate and of this mode in the power of the ovens.
Estos hornos de coque conocidos trabajan principalmente de forma fiable, pero presentan el inconveniente de que se necesitan largos tiempos de coquefacción de hasta 60 horas, para descoquefactar la torta de coque. (Véase p.ej. KNOERZER J.J. et al.: "JEWELL-THOMPSON Non-Recovery Cokemaking" Steel Times, Fuel & Metallurgical Journals Ltd. Londres, RU, tomo 221, Nº 4, 1 de abril de 1993 (01-04-1993), páginas 172-173, 184, XP000365105 ISSN; 0039-095X). J.J. Knoerzer et al. describen en el documento XP000365105 cámaras de horno de coque del tipo "Non-Recovery" y un procedimiento para su funcionamiento. Se describe en especial un modo de procedimiento, en el que la cantidad de aire de combustión necesaria para quemar el gas de coquización se divide en aire primario y aire secundario, en donde el aire primario se introduce en la puerta a través de caños de entrada y el aire secundario, a través de canales de entrada, en el suelo de la cámara de horno de coque. El gas de combustión secundario es guiado a través de un túnel colector en los canales de solera tendidos por encima, en donde se utiliza para calentar la torta de coque. Se describen asimismo modos de procedimiento para controlar la temperatura de coquización, la carga y la exprimición. Se cita la posibilidad de recuperar de energía mediante la forma constructiva "Heat-Recovery". No se describe una disposición especial de piedras moldeadas. Tampoco se indica ninguna posibilidad de conseguir, mediante una modificación del flujo de aire secundario, un acortamiento de los tiempos de coquefacción y de este modo de una mejora de la calidad de coque. De este modo la misión de la invención consiste en hacer patente un horno de coque y un procedimiento, mediante el cual se consigan tiempos de coquefacción más cortos.These known coke ovens work primarily reliably, but have the disadvantage that long coking times of up to 60 hours are needed to uncoke the coke cake. (See eg KNOERZER JJ et al .: "JEWELL-THOMPSON Non-Recovery Cokemaking" Steel Times, Fuel & Metallurgical Journals Ltd. London, UK, volume 221, No. 4, April 1, 1993 (04-04- 1993), pages 172-173, 184, XP000365105 ISSN; 0039-095X). JJ Knoerzer et al . described in document XP000365105 coke oven chambers of the "Non-Recovery" type and a procedure for its operation. A procedure mode is especially described, in which the amount of combustion air necessary to burn the coking gas is divided into primary air and secondary air, where the primary air is introduced into the door through inlet pipes and secondary air, through inlet channels, on the floor of the coke oven chamber. The secondary combustion gas is guided through a collector tunnel in the hearth channels lying above, where it is used to heat the coke cake. Methods of controlling coking temperature, loading and squeezing are also described. The possibility of recovering energy through the constructive form "Heat-Recovery" is cited. A special arrangement of molded stones is not described. Nor is it possible to obtain, by means of a modification of the secondary air flow, a shortening of coking times and thus an improvement in coke quality. In this way the mission of the invention consists in patenting a coke oven and a process, by means of which shorter coking times are achieved.
Ha podido demostrarse que una causa para el tiempo de coquefacción está representada por el suelo de horno, que tiene que soportar la pesada de carbón. Este presenta una considerable resistencia a la conductibilidad térmica, de tal modo que el lado inferior de la pesada de carbón se descoquefacta claramente más lentamente que el lado superior. Por ello la invención resuelve la misión mediante un horno de coque horizontal de comprende una cámara de horno de coque, un suelo de horno de coque y varios canales de gas de escape, que discurren horizontalmente dispuestos por debajo del suelo de horno de coque en la región de la solera de horno. El suelo de horno de coque situado entre la cámara de horno de coque y el canal de gas de escape está estructurado, en dirección vertical, con al menos dos capas y se apoya en las paredes de los canales de gas de escape. Cada una de estas capas está formada por el mismo o diferente material refractario como material de silicio, charnota, etc. El horno de coque conforme a la invención destaca porque la primera capa, según se mira desde la cámara de horno, está formada por un material macizo, y la segunda capa presenta un gran número de aberturas, hendiduras, huecos, pequeños canales, etc., en donde las cámaras de gas de estas aberturas, hendiduras, de estos huecos, canales, etc. están unidos a la cámara de gas del canal de gas de escape que discurre por debajo.It has been shown that a cause for coking time is represented by the oven floor, which It has to withstand heavy coal. This presents a considerable resistance to thermal conductivity, thereby that the lower side of the heavy coal is uncooked clearly more slowly than the upper side. Therefore the invention solves the mission through a horizontal coke oven of comprises a coke oven chamber, an oven floor of coke and several exhaust channels, which run horizontally arranged below the floor of coke oven in the region of the oven hearth. The coke oven floor located between the coke oven chamber and the exhaust gas channel is structured, in a vertical direction, with at least two layers and supports on the walls of the exhaust gas channels. Each of these layers are formed by the same or different material refractory as silicon material, charnota, etc. The oven of coke according to the invention stands out because the first layer, according to it looks from the oven chamber, it is formed by a material solid, and the second layer has a large number of openings, slits, holes, small channels, etc., where the chambers of gas from these openings, crevices, from these holes, channels, etc. they are attached to the gas chamber of the exhaust gas channel that runs below.
La segunda capa presenta de forma ideal una forma curvada de tipo bombeado y la primera capa tiene al menos un lado superior plano, sobre el cual está situada en el funcionamiento según lo establecido la tarta de coque o la pesada de carbón o coque durante el tiempo de coquefacción. Con ello puede mejorarse además el horno de coque, con la finalidad de que entre la primera y la segunda capa esté dispuesta(o) al menos otra(o) capa o elemento de transición.The second layer ideally presents a curved form of pumped type and the first layer has at least one flat top side, on which it is located in operation as established by the coke cake or the heavy coal or coke during coking time. This can be improved also the coke oven, with the purpose of entering the first and the second layer is arranged (or) at least one other (or) layer or transition element.
A las temperaturas presentes de alrededor de 800ºC las proporciones convectivas del transporte de calor son secundarias con relación a la proporción del transporte de calor forzado por la radiación, de tal modo que no tiene que afluir ningún gas en las aberturas, los canales, etc. Con el uso de la segunda capa en forma de un mecanismo de rejilla de este tipo se influye por ello sólo mínimamente en la estática del horno; pero el grosor del suelo de horno de coque que soporta puede reducirse hasta en un 40%. Esto conduce a una considerable reducción de la resistencia media a la conducción térmica del suelo de horno de coque y, como consecuencia de ello, a un acortamiento también considerable del tiempo de coquefacción o a un aumento de la potencia del horno. Un efecto secundario positivo se obtiene por medio de que la mayor rugosidad superficial de la cubierta de canal de escapes conduce a una reducción local de la velocidad de corriente, con lo que por unidad de tiempo se produce también un aumento de la cantidad de calor que puede transmitirse.At the present temperatures of around 800 ° C the convective proportions of heat transport are secondary in relation to the proportion of heat transport forced by radiation, so it doesn't have to flow no gas in openings, channels, etc. With the use of the second layer in the form of such a grid mechanism is it therefore only minimally influences the static of the oven; but Coke oven floor thickness that supports can be reduced up to in 40%. This leads to a considerable reduction of the average resistance to thermal conduction of the furnace floor of coke and, as a result, a shortening also considerable coking time or an increase in oven power. A positive side effect is obtained by means that the greater surface roughness of the channel cover of leaks leads to a local reduction in the speed of current, so that per unit of time there is also a increase in the amount of heat that can be transmitted.
Otra optimización consiste en que la segunda capa está formada por piedras moldeadas, que se componen de un material macizo y se disponen de tal modo, que entre piedras moldeadas adyacentes o de la pared se forman aberturas, hendiduras, huecos, etc. La ventaja de esta estructura es la sencilla transposición, ya que pueden utilizarse las piedras moldeadas idénticas cuneiformes que se utilizan ya para la cubierta de canal sobre toda la superficie y en el estado de la técnica.Another optimization is that the second layer is formed by molded stones, which are composed of a solid material and are arranged in such a way that between stones adjacent or wall moldings are formed openings, slits, gaps, etc. The advantage of this structure is the simple transposition, as molded stones can be used identical cuneiform that are already used for channel cover over the entire surface and in the state of the art.
Una optimización del horno de coque consiste en que la segunda capa está formada por piedras moldeadas, en donde cada piedra moldeada aislada presenta al menos una abertura, hendidura, un hueco, canal, etc. y de forma ideal cada piedra moldeada aislada presenta varia(o)s aberturas, hendiduras, huecos, canales, etc. Con ello pueden combinarse según los requisitos constructivos también las dos posibilidades antes citadas para generar huecos o piedras moldeadas con canales, con piedras moldeadas de material macizo.An optimization of the coke oven consists of that the second layer is formed by molded stones, where each insulated molded stone has at least one opening, slit, a hole, channel, etc. and ideally every stone molded insulated has several openings, slits, holes, channels, etc. This can be combined according to the constructive requirements also the two possibilities before cited to generate holes or molded stones with channels, with molded stones of solid material.
Para determinadas requisitos la sección transversal abierta de las aberturas, hendiduras, los huecos o canales puede ser diferente en la capa inferior. Secciones transversales diferentes de las aberturas permiten una optimización del guiado de gas y de la corriente de calor. De este modo puede producirse en especial que la sección transversal abierta de los dispositivos citados se aumente en la región de las puertas y de las paredes de horno, para hacer posible una distribución uniforme de la corriente de calor en toda la región del canal de guiado hacia fuera del gas. Para el dimensionado exacto de las aberturas pueden calibrarse sus secciones transversales. Por medio de esto puede configurarse uniformemente el proceso de coquefacción del coque, según el tipo de ejecución de la invención, por toda la longitud del horno. Además de esto pueden compensarse carencias de calentamiento con esta clase de configuración de aberturas. Puede obtenerse una mejora adicional de la transición de calor si entre la primera y la segunda capa está dispuesta al menos otra capa, en donde la propia piedra moldeada que forma la primera capa comprende una capa de cubierta y una capa inferior, en donde la capa de cubierta está formada por material macizo y la capa inferior presenta un gran número de aberturas, hendiduras, huecos, canales, etc. y forma esta capa intermedia adicional.For certain requirements the section transverse openings of openings, crevices, gaps or Channels may be different in the lower layer. Sections cross sections other than openings allow optimization of gas guidance and heat flow. This way you can occur in particular that the open cross section of the cited devices are increased in the region of the doors and the oven walls, to make possible a uniform distribution of the heat flow throughout the region of the guidance channel towards out of gas For the exact dimensioning of the openings they can calibrate its cross sections. Through this you can uniformly set up the coke coking process, according to the type of execution of the invention, for the entire length from the oven. In addition to this, deficiencies of heating with this kind of opening configuration. May obtain a further improvement of the heat transition if between the first and second layers are arranged at least one other layer, in where the molded stone itself that forms the first layer comprises a cover layer and a lower layer, where the layer of cover consists of solid material and the bottom layer It has a large number of openings, slits, holes, channels, etc. and form this additional intermediate layer.
Si la primera capa presenta dos lados de caras paralelas y la segunda capa se ha construido arqueada a modo de arco, normalmente es necesario prever una capa intermedia compensadora o elementos de transición, para que la primera capa pueda apoyarse de forma ideal sobre la segunda capa. En este caso una variante de ejecución mejorada consiste en que la capa intermedia o el punto de transición, que están previstos para compensar diferentes contornos de las capas, se componen de piedras moldeadas que presentan al menos una abertura, una hendidura, un hueco, un canal, etc.If the first layer has two sides of faces parallel and the second layer has been built arched by way of arc, it is usually necessary to provide an intermediate layer compensator or transition elements, so that the first layer can ideally rest on the second layer. In this case an improved execution variant is that the layer intermediate or the transition point, which are intended for compensate for different contours of the layers, they are made up of stones molded having at least one opening, a slit, a hollow, a channel, etc.
En el suelo de horno de coque formado por muchas piedras aisladas tienen que realizarse obras de albañilería, con un elevado consumo de tiempo. Este consumo de tiempo puede reducirse considerablemente mediante una variante de ejecución ulterior del horno de coque conforme a la invención, si el suelo de horno de coque está formado en dirección vertical sólo por un segmento de suelo enterizo, que comprende una capa de cubierta y una capa inferior, en donde la capa de cubierta está formada por material macizo y la capa inferior presenta un gran número de aberturas, hendiduras, huecos, canales, etc.On the floor of coke oven formed by many isolated stones have to be done masonry works, with a high time consumption This time consumption can be reduced considerably by means of a further execution variant of the coke oven according to the invention, if the oven floor of coke is formed vertically only by a segment of full soil, comprising a cover layer and a layer bottom, where the cover layer is formed by material solid and the lower layer has a large number of openings, slits, holes, channels, etc.
Estos segmentos de suelo están conformados de forma ideal de tal modo, que estos presentan en el lado inferior un bombeado cóncavo. La capa inferior de estos segmentos de suelo puede formar también, en la ejecución conforme a la invención del procedimiento, la cubierta del canal de gas de escape. En el caso de un funcionamiento según lo establecido del dispositivo las tortas de coque o la pesada de coque se encuentran sobre la capa de cubierta del suelo de horno de coque. La capa de cubierta no está conformada por ello normalmente de forma bombeada, sino que posee una forma constructiva nivelada horizontalmente.These floor segments are made up of ideal form in such a way that these have on the lower side a concave pumped. The bottom layer of these soil segments can also form, in the execution according to the invention of the procedure, the exhaust gas channel cover. In the case of operation as established by the device cakes of coke or coke weighing are on the layer of Coke oven floor cover. The cover layer is not conformed by it normally in a pumped way, but it has a horizontally level constructive form.
Para facilitar la fabricación constructiva del horno de coque las piedras moldeadas de suelo poseen ya ventajosamente, en su forma exterior, el contorno del suelo acabado. De este modo pueden poseer una forma curvada de tipo bombeado, ya como piezas constructivas aisladas, las piedras moldeadas de suelo previstas para la segunda capa. Las piedras moldeadas previstas para la primera capa poseen por el contrario como piedras constructivas aisladas en su lado superior, ventajosamente, una forma plana.To facilitate the constructive manufacturing of coke oven molded floor stones already possess advantageously, in its outer form, the contour of the ground finish. In this way they can have a curved shape of type pumped, already as insulated construction pieces, the stones floor moldings provided for the second layer. The stones molded provided for the first layer possess on the contrary as building stones isolated on its upper side, advantageously, a flat shape.
Para una sencillez constructiva especial de la forma constructiva, las piedras moldeadas de suelo pueden estar también conformadas y estar dimensionadas en su tamaño de tal modo, que en toda su extensión estén adaptadas a la anchura del respectivo canal de gas de escape y al grosor de las paredes de canal de gas de escape. Cada piedra moldeada de suelo aislada recubre después el canal de gas de escape en toda su anchura y está situada con sus extremos sobre las paredes de canal de gas de escape. Un gran número de piedras moldeadas de suelo situadas en paralelo sobre el canal de gas de escape recubre después el canal de gas de escape.For a special constructive simplicity of the constructive form, the ground molded stones can be also shaped and sized in such a way, that in all its extension are adapted to the width of the respective exhaust gas channel and the thickness of the walls of exhaust gas channel. Each molded stone floor insulated it then covers the exhaust gas channel in its full width and is located with its ends on the gas channel walls of escape. A large number of ground molded stones located in parallel over the exhaust gas channel then covers the exhaust gas
Asimismo la invención comprende un procedimiento para producir coque, en el que se usa un horno de coque en una de las formas de ejecución antes citadas.The invention also comprises a method to produce coke, in which a coke oven is used in one of the forms of execution mentioned above.
A continuación se pretende describir con más detalle, con base en las figuras 1 a 3b, a modo de ejemplo algunas variantes de ejecución. La fig. 1 muestra en una representación en corte un horno de coque 1 conocido en forma constructiva horizontal. La verdadera cámara de horno de coque 2 está circundada por los muros exteriores 3 y se abastece de aire de combustióna través del canal de aire primario 9. Los gases de combustión se conducen desde la cámara de horno de coque 2 a través de un canal de pared, el llamado Downcorner 4, hasta los canales de gas de escape 5, que discurren por debajo del suelo de horno de coque 11. Los canales de gas de escape 5 están separados por paredes de separación 6, pero están unidos entre sí de una forma no representada. Por debajo de los canales de gas de escape 5 discurren canales de aire secundarios 8, a través de los cuales puede controlarse la combustión en los canales de gas de escape 5. La pesada de carbón o del coque 10 está situada, en el caso de funcionamiento según lo establecido, como pesada o torta comprimida sobre el suelo de horno de coque 11.The following is intended to describe with more detail, based on figures 1 to 3b, by way of example some execution variants. Fig. 1 sample in a representation in cut a known coke oven 1 constructively horizontal. The true coke oven chamber 2 is surrounded by the outer walls 3 and is supplied with combustion air through the primary air channel 9. The flue gases are lead from the coke oven chamber 2 through a channel wall, the so-called Downcorner 4, to the gas channels of Exhaust 5, which run under the floor of coke oven 11. The exhaust gas channels 5 are separated by walls of separation 6, but they are linked together in a non- represented. Below the exhaust gas channels 5 secondary air channels 8 run through which combustion can be controlled in the exhaust gas channels 5. Weighing coal or coke 10 is located, in the case of operation as established, such as heavy or compressed cake on the floor of coke oven 11.
La representación en corte de la fig. 2a muestra
en detalle el suelo de horno de coque 11. El suelo de horno de
coque 11 estructurado con las dos capas 11a y 11b está colocado
sobre las paredes de separación, que están formadas por piedras de
pared de separación 20. La verdadera superficie del suelo de horno
de coque 11 está formada por placas de suelo 15 planas, que están
colocadas encima de las piedras de transición 13 horizontales.
Estas piedras de transición 13 horizontales forman el cierre
vertical de las paredes de separación 6. Por debajo de la piedras
de transición 13 están dispuestas dos piedras de apoyo 17, que por
su lado descansan sobre las coronas de muro de la respectiva pared
de separación 6. La pared de separación 6 está formada por piedras
moldeadas 20 paralelepipédicas. En los flancos de las piedras de
apoyo 17 se apoya la cubierta 12 del canal de gas de escape 5, que
está conformada como arco y está formada por un gran número de
piedras de cubierta 16 cuneiformes. Las piedras de cubierta 16
están dispuestas de tal modo, que entre las piedras de cubierta 16
se obtiene siempre un hueco 18 o canal, como se ha representado en
la vista inferior de la cubierta 12 en la fig. 2a. Otra ventaja de
la invención estriba en que con el mecanismo de rejilla en la vista
inferior 11b se necesita menos material de construcción, lo que es
ventajoso desde el punto de vista
económico.The sectional representation of fig. 2a shows in detail the coke oven floor 11. The coke oven floor 11 structured with the two layers 11a and 11b is placed on the separation walls, which are formed by separation wall stones 20. The true surface of the Coke oven floor 11 is formed by flat floor plates 15, which are placed on top of the horizontal transition stones 13. These horizontal transition stones 13 form the vertical closure of the separation walls 6. Two support stones 17 are arranged below the transition stones 13, which on their side rest on the wall crowns of the respective separation wall 6 The separation wall 6 is formed by parallelepiped molded stones 20. The cover 12 of the exhaust gas channel 5 is supported on the flanks of the support stones 17, which is formed as an arc and is formed by a large number of cuneiform cover stones 16. The cover stones 16 are arranged in such a way that a gap 18 or channel is always obtained between the cover stones 16, as shown in the bottom view of the cover 12 in fig. 2nd. Another advantage of the invention is that with the grid mechanism in the bottom view 11b less construction material is needed, which is advantageous from the point of view
economic.
